VAP^3®/PA Features and Benefits

Primary Flow Element - VAP^3®/PA (Particulate Applications)

VAP^3®/PA is designed for particulate-laden applications. Can be placed in heavily particulate/condensate-laden environments while still measuring accurately and reliably without being prone to plugging problems.

Primary Flow Element - VAP^3®/SA (Superior Accuracy)

Ideally designed to provide accurate differential pressure outputs for precise air flow measurement in process applications, the VAP^3®/SA is suitable for relatively clean process environments (such as clean flows or filtered gas streams), where high accuracy is required for measurement and control.

Parallel Plate Cross Sectional Design-

Minimizes turbulence at the sensing ports, preventing particulate build up and also designed for high turndown applications

Multiple Differential Pressure- Sensing Ports

Velocity averaging throughout the full traverse of the duct with multiple pitot array

Durable Materials of Construction

Constructed from extruded 6063 series aluminum with a final process Teflon^® hard anodized coating, yielding a surface hardness of Rockwell 65C.

Basic Installation

Each VAP^3®/PA and VAP^3®/SA Pitot probes can be inserted into the duct utilizing a pre-fabricated weld on insertion port. When multiple probes are needed within the duct, the total and static sensing ports can be manifolded together.

Negligible Pressure Loss

Due to the streamline, narrow cross-section of the Parallel Plate Pitot design, the VAP^3®/PA and VAP^3®/SA will not restrict the airflow, therefore there will be minimal, if not negligible pressure drop across the measurement area. Integrated temperature elements are available to further reduce in-duct obstructions

In Duct Sensors are Passive

There are no active, electronic components or moving parts that are installed within the air stream, therefore eliminating maintenance costs and ensuring reliability

Engineered Solutions

Heated Pitots, High Velocities, Large duct installations (VAP^3®/XL Pitots (Up to 240 inches)), and much more to meet customer specific needs
